More particularly, this invention is directed to a digger, shaker, windrowing and inverting apparatus for peanut plant row crops operable for digging peanut plants growing in a pair of adjacent rows, windrowing the dug peanut plants, and simultaneously drying and conditioning the peanuts for subsequent collection of the peanuts in a threshing operation.

In the process of harvesting peanut crops, the peanut laden plants are first dug and left on top of the ground for subsequent harvesting. Since several days may intervene between digging and combining, it is possible for the peanuts to rot if they remain directly in contact with the ground; and, for this reason, the digging of the peanuts is effected by machines which dig the plants, shake them to remove some or most of the soil which clings inevitably to the peanuts and then places the from the elevated discharge end of the conveyor which receives the plants as dug and conveys them upwardly to the tines while shaking the plants to remove debris and soil therefrom. The platform of tines or guide fingers may be effective essentially alone, or in conjunction with conveyor discharge action, to provide the plant inverting action. In any case, the devices of the prior art tend to produce erratic inverting and, at best, to provide windrows in which peanuts are not uniformly elevated out of contact with the ground but are instead disposed more or less along the opposite sides of the windrow. This may be caused either by failure to fully invert the plants so that the vines are not directly beneath the peanuts, or by inverting action which is too strenuous, leading to the same results by reason of rotating the plants past the fully inverted position. These defects not only lead to inferior drying and consequent possibility of peanut damage by rotting, but also produce windrows which cannot be efficiently gathered by the threshing equipment.

SUMMARY OF THE INVENTION The above indicated disadvantages of the prior art have been overcome by the present invention which basically includes an arrangement'of'a peanut diggershaker inverter wherein the inversion of the plants of a pair of adjacent rows is so controlled as to cause the plants when discharged, to crowd together along a compact windrow in which all of the peanuts lie closely together along the top center portion of the windrow. In this way, the peanuts areexposed for maximum drying action and are, as well, most effectively placed for subsequent gathering and separation by the threshing equipment.

Essentially, the present invention involves an arrangement wherein the plants of two rows are dug and root or peanut portions deposited on a conveyor for movement along separate paths to a point of elevated discharge. One important feature of the present invention is the provision of deflecting means associated with the conveying means for contacting and effecting an angular displacement of the plants moving along the elevated path by the conveying movement to the elevated discharge position. Rotatable disc directing means are located on the harvesting apparatus in a position to receive the peanut vines discharged by the conveying means and operable for directing the vines in their angular oriented position rearwardly to the windrowing apparatus. The windrowing apparatus includes two sets of rearwardly directed tine means laterally spaced relative to each other to define a windrow space therebetween.

An additional important feature of the present invention is the frame support means provided for supporting the digging apparatus, conveying means, vine deflecting means, rotatable disc directing means and windrowing tine means in a compact operative arrangement which will provide maximum stability and control during operation.

Accordingly, it is a primary object of the present invention to provide a root crop harvesting apparatus which is operable for digging root crops from their growing implacement in the ground, orienting the plants in an inverted position with the root crop portion located above the plant portion and removing soil therefrom in the process. I

Another object of the present invention is to provide a root crop harvesting apparatus which is operable for digging root crops from a pair of adjacent rows, forming the root crops from the two rows into a compact windrow located between the dug rows and simultaneously inverting theroot crop in the windrow forming operation.

I A further object of this invention is to provide a root crop harvesting apparatus which will effectively dig and remove a root crop from its growing implacement in the ground, advance the dug root crop upwardly along an inclined path, while simultaneously removing soil therefrom and orienting the root crop from a substantially upright position to a substantially horizontal posi tion.

A still further object of this invention is to provide a root crop harvesting apparatus having deflecting means operable for effecting an angular displacement of a plant in response to conveying movement in a harvesting operation.

Still another object of this invention is to provide a root crop harvesting apparatus having effective windrowing means operable for windrowing root crop plants dug from a pair of adjacent rows, and in response to discharge by plant conveying means.

Yet another object of this invention is to provide a root crop harvesting apparatus having formed tine directing means operable for effecting an angular displacement of a root crop plant moving relative thereto and operable for simultaneously displacing the root crop plant from a first path of movement to a laterally displaced position for discharge.

Still another object of this invention is to provide a frame support means operable for supporting various reference numerals have been used to refer to like parts throughout the several figures, and wherein:

The support mechanism including supporting frame 140 and chain linkage means 144 will permit the deflecting rods 96 to deflect upwardly relative to the conveyor mechanism 100, but will maintain the deflecting rods 96 in spaced position outwardly of the conveyor lug elements 109, substantially as shown in FIG. 4. Chain linkage means 144 is secured to the supporting frame 140 by means of hook elements 145. The frame 140 includes a number of spaced hook elements 145 which will permit adjustment of the chain linkage 144 relative to the supporting frame 140, thereby allowing the lateral spacing or angular converging relationship of the deflecting rod 96 to be varied.

WINDROWING MEANS As shown in FIGS. 1-4, the windrowing means 150 is supported to the rear and below the discharge end of the conveyor mechanism by means of the framework support plates 40, 41 described hereinabove. The support plates 40, 41 are provided with adjusting means such as a plurality of spaced openings (not shown) whereby the windrowing means can be precisely positioned parallel to frame members 27, 28. The windrowing means will be described with reference to a rotatable peanut vine directing means 151 and a pair of windrowing assemblies 170, 180.

The rotatable peanut directing means includes a support shaft 152 rotatably supported by conventional bearing means within the plate elements 40, 41. As shown in FIG. 8, a plurality of crop directing disc elements 153 are coaxially supported on shaft 152. Each of the disc elements 153 is constructed in the shape of an eight-sided figure, with the intersecting points between each of the sides of the figure being slightly rounded to present a smooth outer edge for contacting and directing the peanut laden vines rearwardly in a harvesting operation. Each of the crop directing disc 153 is provided with a substantially square opening concentrically arranged therein and detailed for receiving a complementary square surface portion of shaft 152, whereby rotation of shaft 152 will effect a corresponding rotation of disc 153.

In an assembled relationship, the axial edge of a collar 1530 of one disc is in abutting contact with an axial edge of an adjacent disc collar and the projections 153b are fitted within the aligned complementary openings 153a. The crop directing discs 153 are secured in an axially set position on rotatable shaft 152 by means of a pair of end plate members 154. The end plate members 154 include axially extending bracket means 155 which are supported on opposite sides of the shaft 152 and include a conventional connecting bolt means 156 extending through complementary openings on shaft 152 and elongated adjustment slots 155a formed in brackets 155.

The eight-sided configuration of disc elements 153, with smooth rounded corners and with the collar means 153a will ensure that the peanut laden vines are directed rearwardly without becoming entangled around the rotary support shaft 152.

The number of discs 153 and axial dimensions of disc collars 153a are detailed such that the rotary crop directing means will extend substantially the full width of the conveyor mechanism 100, as shown in FIG. 3. The crop directing shaft 152 is driven in a counterclockwise direction, as shown in FIG. 4, by means of a sprocket 157 fixed to the leftward extended end of shaft 152 on an opposite side of plate 41. Sprocket 157 is driven by a conventional chain 158. Chain 158 is in driving engagement with sprocket 157 and sprocket 159. Sprocket 159 is fixed to a left extended end of shaft 49. A rotary movement of shaft 49 in a counter clockwise direction (FIG. 4) will effect a corresponding counterclockwise direction of movement of sprocket 159, chain 158, sprocket 157 and shaft 152. A protective housing means 168 is provided on the frame support means for surrounding the chain and sprocket drive means 157-159.

The windrowing means 150 includes a pair of tine assemblies 170, 180. Each of the tine assemblies 170, 180 includes a pair of inboard tines 171, 181 and four outboard tines 172, 182, respectively. The tine assemblies 170, 180 are supported on the windrowing means 150 in laterally spaced relationship to define a free space therebetween. The free space between the tine assemblies 170, 180 is centered relative to the conveyor mechanism and centered relative to the digging assemblies 81, 82, whereby a pair of adjacent rows being dug by the digging assemblies 81, 82 and conveyed upwardly by the conveying mechanism 100 can be directed inwardly to a windrow aligned with the free space between the laterally spaced tine assemblies 170, 180. 4

As shown in FIGS. 3 and 4, each of the tines of the two tine assemblies 170, 180 are secured to a crosssupporting bar 190. Opposite ends of the cross-supporting bar 190 are secured to a lower end of the supporting plate members 40, 41. Opposite ends of the'bar 190 include a pair of oppositely directing bracket members 191, 192 which are provided thereon in detailed location to be in abutting contact with the internal surface of plate members 40, 41. Bracket means 191, 192 are secured to plate members 40, 41 by means of a pair of conventional connecting bolts 193 which are inserted through openings provided in brackets 191, 192 and aligned openings 194 provided in plate members 40, 41.

Adjustment of the supporting bar 190 relative to the plates 40, 41 is provided by means of a plurality of openings 194. Openings 194 are formed in plate members 40, 41 along an arcuate path having a radius concentric with the axis of rotatable shaft 152. The detailed location of the openings 194 relative to the axis of shaft 152 will permit the tine elements to be angularly adjusted relative to frame members 27 and 28 about the axis of shaft 152. Each of the tine elements of the two tine assemblies 1'70, 180 includes a substantially U-shaped connecting member 195 detailed to be inserted around the supporting bar 190, substantially as shown in FIG. 3. A tine member is secured in a laterally set position relative to bar 190 by means of a conventional connecting bolt 196 which is inserted through complementary openings provided in the legs of the U- shaped member 195 and through the connecting bar 190.

As shown in FIG. 4,'each of the tine elements of the two tine assemblies 170, 180-extends upwardly from supporting bar 190 around the rotatable directing means in a counterclockwise direction and includes a rearwardly extended portion. The tine elements of the two tine assemblies 170, 180 are'detailed in lateral spacing relative to the rotatable crop directing means such that a tine is located between adjacent axially spaced disc elements 153, as shown in FIG. 3. The

height of the tine elements relative to the rotatable crop directing means 150 is detailed such that the tines are located below the outer circumferential edge and spaced from the collars 153a of the crop directing discs 153, as shown in FIG. 4.

As shown in FIGS. 3, 4, 6 and '7, the two inboard tines 171, 181 of each of the tine assemblies extend upwardly over the rotatable crop directing drum 153 and extend rearwardly therefrom in a downwardly inclined relationship. The inboard tines 171, 181 are longitudinally aligned in substantially parallel relationship relative to each other and are aligned relative to the path of movement of peanut vines moving upwardly over the conveyor mechanism 100. The inboard tines 171, 181 extend downwardly and terminate in an end portion 171a, 181a arranged substantially parallel to the operating ground surface. The length and height of inboard tines 171, 181 are detailed such that the end portions 171a, 181a will remain in contact with the peanuts on a vine after the vine has contacted the ground and is supported thereon, substantially as shown in FIG. 7. With the peanut laden vines in contact with the ground and the peanuts engaged by tine end portions 171a, 181a, a forward motion of the tines in a harvest- I ing operation will produce a slight dragging and twisting effect of the vines as the peanuts are displaced from tine end portions 171a, 181a thereby assuring that the vines are completely inverted with the peanuts supported above the vines.

As shown in FIGS. 3, 4, 6 and 7, the outboard tines 172, 182, of each of the tine assemblies include four tine elements. Each of the outboard tine elements 172, 182 extends upwardly from the cross-supporting bar 190 in a counterclockwise direction around the surface of drum 153, substantially as shown in FIG. 4. Outboard tine elements 172, 182 extend rearwardly in a first direction substantially parallel to each other and longitudinally aligned relative to the path of peanuts moving up the conveyor mechanism and terminate in angularly disposed end portions 172a, 182a. The outboard tines 172a, 182a also are inclined downwardly through various angular inclinations. The various angular inclinations of the outboard tines 172a, 182a are detailed such that the outboard tine located closest to the inboard tines includes an end portion which is located substantially above the outermost inboard tine, with each of the other outboard tines being vertically spaced thereabove, as the tine element moves laterally outward, as shown in FIGS. 5-7.

The tine assemblies 170, are laterally spaced relative to each other and detailed in fore-and-aft alignment and angular inclination whereby a peanut vine moving rearwardly on the conveyor mechanism 100 and falling on the crop directing mechanism 151 ,will be directed rearwardly such that the peanut laden portion of the vine contacts the outboard tines 1'72, 182, substantially as shown in FIGS. 6 and 7 whereby the vine portions are caused to fall downwardly within the free space located between the two tine assemblies 170, 180. A contact of the peanut laden portion of the vine by the outboard tines 172, 182 will restrict movement thereof and thereby effect an angular displacement of the peanut vines through substantially ninety degrees, whereby the peanuts will be. inverted above the vines,

as shown in FIG. 7.

I MODIFICATION OF THE WINDROWING MEANS As shown in FIGS. 1 l and 12, a modified windrowing means 150a is provided. The modified windrowing means 150a is for use in certain soil conditions where excessive amounts of soil are retained on the peanuts after having been dug and moved along the elevated paths by the conveyor means. The windrowing means 150a shown in FIGS. 11 and 12 will provide additional means for aiding in the separation of soil clinging to the cluster of peanuts. The windrowing means 150a is similar to the windrowing means 150 described herein above except that two rotary crop directing means are provided for directing the peanut laden vines rearwardly from the discharge end of the conveyor onto the windrowing tines.

As shown in FIGS. 11 and 12, the modified windrowing assembly 150a includes a pair of mounting plates 40a and 41a which are adapted to be attached to the underside of frame elements 27, 28 in substantially the same manner as mounting of the plate members 40, 41. Bracing link members 40b, 41b are connected between lower depending ends of the plate members 40a, 41a and the rearwardly extended ends of the frame elements 23, 24. The bracing link members 40b, 41b are secured adjacent their opposite ends in a bracing relationship by means of conventional connecting bolt means 40c, 41c.

A support shaft 1520 is rotatably supported by conventional bearing means within the plate members 40a, 41a. A second support shaft 152b is rotatably supported by conventional bearing means within the plate elements 40a, 41a. Shaft 152b is supported in parallel spaced relationship relative to shaft 152a. The axis of shaft 152b is detailed to be located below and rearwardly spaced of the axis of shaft 152a. Each of the rotatable shafts 152a, 152b are provided with a plurality of crop directing disc elements 153. Reference is made to the above description of the windrowing means 150 for details of construction of the crop directing disc 153.

As shown in FIG. 12, the rotatable crop directing disc 153 supported on shaft 152b is detailed to be axially spaced substantially midway between the rotatable crop directing disc 153 supported on shaft 1520. The spacing of shafts 152a, 152b are detailed such that the crop directing disc 153 of the two shafts are overlapping relative to each other, substantially as shown in FIGS. 11 and 12.

Shaft 152a is driven in a harvesting operation by means of a conventional chain 158a which is supported in driving engagement with a first sprocket 157a mounted on an extended end of shaft 152 and supported in driving engagement with a second sprocket 159a supported on an extended end of rotary drive shaft 49. In a harvesting operation, shaft 152a and its supported crop directing disc 153 will be driven in a counterclockwise direction, as shown in FIG. 11. A drive from shaft 152a is delivered to shaft 152b by means of a chain 1581;. Chain 158b is supported in driving engagement with a first sprocket 1571: which is fixed to an extended end of shaft 152a opposite from sprocket 157a and supported in driving engagement with a second sprocket means 157c supported on an extended end of shaft 152b, as shown in FIG. 12. A counterclockwise rotation of shaft 152a will effect a corresponding counterclockwise rotation of shaft 152!) with its crop directing disc 153.

The windrowing means shown in FIGS. 11 and 12 include a pair of tine assemblies 170a, 180a. The tine assemblies 170a, 180a are substantially identical to the tine assemblies described hereinabove in the first windrowing means 150 and reference is made to the above description of the tine assemblies for details of the tine assemblies 170a, 180a.

In utilizing the digger shaker inverter embodying the principles of the present invention, either of the windrowing means 150 shown in FIGS. 1-7 or the windrowing means 150a shown in FIGS. 11 and 12 can be utilized therewith. As indicated hereinabove, the particular windrowing means which is to be utilized will be controlled by the soil conditions in which the peanuts are grown.

OPERATION In operation, the peanut harvesting apparatus embodying the principles of the present invention is supported on a conventional tractor vehicle by means of a conventional three-point linkage system which is connected to the framework connecting pins 20-22. After the three-point linkage system of a suitable tractor vehicle has been connected to the pins 20-22, the power input drive shaft 62 is connected by suitable conventional universal connecting means to a power takeoff of the tractor vehicle. A rotary driving input to shaft 62 is effected by operating conventional control mechanism on the tractor which will in turn effect a rotation of the conveyor mechanism 100 and rotatable crop directing means 151.

After the digger shaker inverter has been supported on a tractor, a peanut digging and windrowing operation is effected by moving the vehicle with peanut digger shaker inverter into position straddling a pair of adjacent rows to be dug and adjusting the linkage support mechanism of the tractor to allow the transverse cutting plates 88 to penetrate the ground sufficiently to sever the tap root and the root system beneath the clusters of peanuts and with the rolling colter disc 97, 97f and 97g engaging the ground tosever the vines between adjacent rows as described above. With the digging assemblies properly adjusted, a peanut digging operation is performed by advancing the tractor longitudinally along the rows.

After the root system has been severed below the cluster of peanuts, tine elements 94 of the digging assemblies will elevate the peanuts to a position above the ground. The spaced tines 94 will permit a'substantial portion of the soil to be displaced from the peanuts through the space therebetween. A continued movement of the digging assemblies will elevate the peanuts above the ground and will allow the conveyor mechanism 100 including transverse conveyor bars with lug members 109 to engage the peanuts and advance the peanuts upwardly along inclined spaced parallel paths. As the peanuts move upwardly along the inclined spaced parallel paths, deflecting rods 96 will contact the vine or foliage portion and thereby effect an angular displacement of the vines inwardly toward each other. The angular displacement effected by the deflecting rods 96 will be substantially thereby moving the peanuts from a substantially upright growing position to a substantially horizontal position lying on the conveyor 100. Movement of peanuts by the conveyor 100 will also shake loose any additional soil clinging to the peanuts and will allow the soil to fall freely to the ground in front of the windrow being formed.

As the plants reach the rearward or discharge end of the conveyor mechanism, they are lifted gently by the lifter rods 125, previously described, out of the engagement with the lugs 109 and are thus expelled gently rearward to fall by gravity onto the rotatable crop directing means 151.

Peanut plants which are discharged by the conveyor mechanism 100 will be oriented in a substantially horizontal position with the vine portions directed inwardly toward each other and with the peanut portions directed outwardly. The peanut plants discharged by the conveyor mechanism will fall by gravity onto the rotatable crop directing disc elements 156 in the horizontal position and will be directed by the disc elements 156 rearwardly onto the windrowing tine assemblies 170, 180. As the peanut plants are directed rearwardly onto the tine assemblies 170, 180, the peanut portion of the plants will contact the outboard tines 1172, 182 substantially as shown in FIGS. -7 thereby restricting the downward fall of the peanut portion of the plants. Since the peanut vine portions havebeen displaced inward through a first ninety degree angular rotation by the deflecting rods 96, the vine portions will be located substantially above the free space between the two windrowing assemblies 170, 180 and will be allowed to fall freely to the ground within the free space. As the peanut vines fall by gravity to the ground the outboard tines 172, 182 will effect a second ninety degree angular rotation of the peanut vines thereby positioning the peanut portion above the vines. Further, in the process of inverting the peanut vines, the windrowing tine assemblies 170, 180 will displace the peanuts inwardly into a windrow which is centered in the free space between the tine assemblies and will be substantially centered between the pair of adjacent rows being dug.

lt now becomes apparent that the illustrative embodiment embodying the principles of the present invention is capable of obtaining the above stated objects and advantages. It is obvious that those skilled in the art may make modifications in the details of construction without departing from the spirit of the invention which is to be limited only by the scope of the appended claims.
